An authenticated member receives 404 when the feature is disabled. Account membership is checked before the feature and role; nonmembers receive 401. This controller reads and changes routing profiles only; it accepts no provider keys or model selections. Separate provider-key and routing APIs remain owned by ENG-4915/ENG-5860; ENG-5876 reconciles their contract with I-30. Accepts top-level profile and lock_version only (parameter wrapping is disabled). Missing or malformed inputs return 422 invalid_params. A stale version returns 409 stale before profile validation. An unchanged profile is a no-op after the lock check. A changed profile writes an account policy and audit event atomically. A pinned profile cannot be changed by customers. Unknown additional fields are ignored. Provider-key/model validation is not performed here. ## OpenAPI ````yaml /api-reference/openapi.json patch /api/v1/accounts/{account_id}/model_settings openapi: 3.0.4 info: title: Tied API description: >- The Tied REST API.
